Question 1.1
What is the definition of a computer?
3
Answer 1.1
An electronic device which operates within a
binary digital system and has 4 functions.
4
Question 1.2
What are the four functions of a computer?
5
Answer 1.2
The four functions of a computer are 1. Accept
data 2. Process data 3. Produce output 4. Storage
6
Question 1.3
What is the difference between data and
information?
7
Answer 1.3
Data are the isolated facts that are input into
the computer. Information is processed data.
8
Question 1.4
What is a port?
9
Answer 1.4
A port is a connection for a peripheral device
such as a printer or a modem.
10
Question 1.5
Define a binary digital system.
11
Answer 1.5
A binary digital system refers to a system which
works within 2 states, in this case on/off. This
on/off correlates to the binary digits of a 1 or
a 0. These two digits are the only two digits a
computer can interpret.
12
Question 2.1
The CPU is a.) the microprocessor b.) the system
unit c.) permanent storage
13
Answer 2.1
The CPU is a) the microprocessor. It only
communicates with RAM within the computer. Its
primary function is to process instructions with
the machine cycle steps of fetch, interpret, and
execute. It has no storage except small temporary
register storage. The system unit is the tower
which houses much of the computer hardware.
14
Question 2.2
CPU speed is measured in a.) kilobytes b.)
gigabytes c.) megahertz
15
Answer 2.2
The answer is c.) megahertz and refers to the
number of instructions (in million units) the CPU
can process per second.
16
Question 2.3
What are the two parts of the CPU?
17
Answer 2.3
The two parts of the CPU are the ALU -
arithmetic logic unit the control unit.
18
Question 2.4
What is the definition of a register?
19
Answer 2.4
A register is fast accessing storage inside the
CPU.
20
Question 2.5
What is the relationship of the parts of the
CPU to the machine cycle?
21
Answer 2.5
The control unit performs the fetch/interpret
part of the cycle the ALU performs the execute
part of the cycle.
22
Question 3.1
RAM is a.) permanent storage b.) temporary
storage for data awaiting processing by
the CPU c.) the same as cache
23
Answer 3.1
RAM is temporary storage for instructions and
data awaiting processing by the CPU. Cache is a
type of fast accessing intermediate memory. It
is smaller than RAM and is searched first before
RAM access to speed memory access.
24
Question 3.2
The smallest unit of storage in the computer
is a.) bit b.) byte c.) word size
25
Answer 3.2
The answer is a.) bit. A byte is composed of 8
bits. Word size refers to how many bytes a
register can hold.
26
Question 3.3
The largest unit of storage in the computer out
of the 3 below is a.) kilobyte b.) gigabyte c.)
megabyte
27
Answer 3.3
The answer is b.) gigabyte.
28
Question 3.4
What is the definition of cache?
29
Answer 3.4
Cache is fast accessing intermediate memory.
30
Question 3.5
Which of the following is true about cache a.)
permanent and large storage b.) speeds up the
operations of the computer c.) increases the cost
of the computer (Are you finding more than one
answer for this question?)
31
Answer 3.5
There is more than one answer. Both b and c are
correct. Cache will speed up computer operations
and increase the cost of the computer.
32
Question 4.1
Secondary storage is for a.) permanent storage
of large amounts of data and information b.)
consists of disks and drives c.) both a and b
33
Answer 4.1
The answer is c) both a and b. Secondary
storage is additional permanent storage in the
form of floppy disks CDs hard disks most
recently DVDs Its value is in its capacity to
storage large amounts of data and information.
34
Question 4.2
What are the two parts of secondary storage? a.)
sectors and tracks b.) disks and drives c.)
floppy and hard drives
35
Answer 4.2
The two parts of secondary storage is b.) the
disk which stores the information and the drive
which reads the disks Sectors and tracks are the
parts of the disks. Floppy and hard drives are
only two of the four types of secondary storage.
36
Question 4.3
Which of the following works as magnetic
storage? a.) floppy and hard disks b.) CDs c.)
DVDs
37
Answer 4.3
The answer is a) floppy and hard disks store
information using magnetic properties. CDs and
DVDs store information using light.
38
Question 4.4
Of the following, which type of secondary
storage is the largest? a.) CDs b.) floppy
disks c.) hard disks
39
Answer 4.4
The answer is a) CDs will store the largest
amount of information.
40
Question 4.5
What is a disk crash?
41
Answer 4.5
A disk crash occurs when the read/write
head, (the arm that sits over the disks and reads
it) touches the disk and damages the information
surface.
42
Question 5.1
To represent numbers in the computer a _________
system is used? a.) base 2 b.) base 10 c.) ASCII
code
43
Answer 5.1
The answer is a.) base 2. Base 10 is the number
system we use everyday.
44
Question 5.2
How are letters represented by binary digits?
